The Big Apple, Apple and Mecca

Apple's black cube store on Fifth Avenue has offended Muslims by reminding some of the Ka'ba, the black stone cube in Mecca which is the ultimate destination of the Haj. Why Muslims take offense to images of the Prophet while worshipping a cube of black rock, is beyond me, but it seems to be a religion full of contradictions. Of course, the Apple Store is a black box full of technology, while the Ka'ba is just a block of stone. It seems symbolic, no?
